IOS 13 WKWebView不再显示pdf文件

iOS 13 WKWebView not showing pdf file anymore(IOS 13 WKWebView不再显示pdf文件)

问题描述

let myURL = URL(string:"somefileurl.pdf") // If I hit this url in safari, It will download a pdf file.
let myRequest = URLRequest(url: myURL!)
webViewPdf.load(myRequest)  

推荐答案

我计算出响应‘Content-Type是"应用程序/八位字节流"，而不是"应用程序/pdf"

if let myURL = URL(string:"somefileurl.pdf") {
    if let data = try? Data(contentsOf: myURL) {
       webViewPdf.load(data, mimeType: "application/pdf", characterEncodingName: "", baseURL: myURL)
    }
}
